TEMPLET.

Specification of Letters Patent.

Patented Jan. 28, 1908.

To all wt am it may concern:

Be it known that I, HARRY B. Asn, a subj ect of the King of GreatBritain, residing at St. Louis, State of Missouri, have invented certainnew and useful Improvements in Templets, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, forming a part hereof.

My invention has relation to improve ments in adjustable templets; andit consists in the novel construction and arrangement of parts morefully set forth in the specification and pointed out in the claims.

In the drawings, Figure 1 is a perspective view of my invention appliedto an I-beam; Fig. 2 is a top plan of the templet Fig. 3 is an end view;Fig. 4 is a side elevation of one end of the templet; Fig. 5 is avertical longitudinal section on the line 5.5 of Fig. 2 taken throughone of the adjustable sliding blocks; Fig. 6 is a vertical transversesection on the line 6-6 of Fig. 2 Fig. 7 is a perspective of.

one of the sliding gage blocks; and Fig. 8 is a top plan showing agage-block with centering hole between the edge of the templet andcenter of the block.

The present invention has relation to templets for marking the centersof holes to be punched or drilled in structural members such as plates,channel-bars, Ibeams, T- bars, angle-bars, and in fact any kind ofmember entering into engineering and architectural constructions. Itsobject is to dispense with the use of individual templets improvised foreach and every separate piece of work, and to substitute asingle templetcapable of adjustment to any size or character of work and serviceableunder all circumstances; a further object is to facilitate the layingout or marking of centers, thereby saving time and labor, all as willherein more fully appear from a detailed description of the inventionwhich is as follows:

Referring to the drawings, B, represents an I-beam along the flange ofwhich the centers are to be marked. The templet is composed of sidechannel members 1, 1, preferab y of wood, and preferably too of twogrooved sections secured together by means of countersunk screws 2,(Fig. 6). The channels, however, can be made if desired, out of a singlepiece of wood grooved out to form a suitable way or track for thesliding gage-blocks presently to be referred to. The

opposite upper ends of the channels are connected by'transverse metallicplates 3, and the opposite lower ends by similar metallic plates 3preferably countersunk so as to be flush with the bottom surfaces of thechannels. Along the top of each channel is secured a scale-plate 4graduated to inches and fractions thereof, (or to any convenientsubdivisions) the ends of the plates 4 extending under the cross plates3 to raise the latter slightly above the upper surface of the channelsthereby forming a slight clearance for the free passage of thegage-blocks into and out of the grooves of the channel members 1.

The channel members 1, I, joined together at their opposite ends in themanner indicated, form a longitudinal frame for the re ception of thegage-blocks G. Each block is composed of two sections g, g respectively(Fig. 7) separated along a horizontal plane of division, and terminatingin heads 5 which are received by, and slide in the grooves or channelsof the channel members 1, 1, so that the blocks can be shifted to anyposition along the scales 4. The center of each block has marked thereonan index line 6 disposed the length of the block and extending acrossthe frame, which line registers or cooperates with the scale-marks onthe plates 4, so that any block can be accurately positioned along suchscale. When any block has been shifted to its proper position, it isclamped in place to the frame by means of the clamping screws 7 carriedat the diagonal corners of the section g, the inner ends of the screwsbearing against section g, so that by driving the screws home, theeffect will be to spread the sections g, g apart, and thus clamp themsecurely in place to the frame in which they are otherwise free toslide. The hole h of the block G through which the center punch P isinserted may be at any convenient point along the index line 6. In themain figures (1 to 7 inclusive) the hole his in the center of the block;in the modification Fig. 8, the hole It is nearer the ruled plate 4 theposition of the hole depending on the position the holes to be drilledshall occupy relatively to the edge of the structural member operatedon.

For very long frames a solid or imperforate block G may be interposed atconvenient points between the perforated blocks to insure stiffness forthe frame. As best seen in Figs. 3 and 6, the blocks G, G areconveniently inserted intothe frame from either end thereof, asufficient clearance being left between the upper and lower faces of theblocks and the transverse plates 3, 3. In Fig. 2, the first two blocksare set three inches apart, the first at the two inch mark on the scale,and the second opposite the five inch division.

The frame can be provided With any variety and number of blocksdepending on the kind of work to be done, and any blocks not needed forthe gaging of centers may be temporarily removed from the frame. Arepresents a clamp by which the templet is secured to the structuralmember;

Having described my invention, what I claim is:

1. A templet comprising a longitudinal frame composed of side channelmembers, transverse terminal plates connecting the adjacent ends of'thechannels, gage-blocks mounted .in the frame and sliding in the waysformed by the channels of the side members, each block being composed oftwo sections their adjacent faces being in a plane parallel to the upperand lower faces of the frame, screws mounted in one section and havingtheir inner ends bearing against the adjacent section of the blockwhereby upon driving home the said screws the sections are forced intofrictional engagement with the walls of the channels and thus clamped inposition, the blocks being provided with holes for the passagetherethrough of a centering punch, a scale marked along each side memberof the frame, and an index on each block cooperating with the marks onthe scale, the blocks being insertible into the channels of the framefrom either end thereof.

2. A templet comprising a longitudinal frame having a suitable scale, aseries of gage-blocks mounted in the frame and adapted to be shifted onthe same to predetermined distances apart from one another, meanscarried by the blocks for securing the same to the frame in theiradjusted position, the blocks being provided with holes for thereception of centering punches or tools.

In testimony whereof I afiix my signature, in presence of two witnesses.
